It is more of in Xinlu's POV: I got tempted by his drunk face and offered my sexual services and asked him consent when he is not on right headspace to give consent and still I did my charity sexual advances and tire my partner out...
Yuri has to even gaslight himself hard on it- that he loved it-
The dynamic of their relationship is Yuri likes Xinlu but is mature and collected not to cross boundaries and therefore tries not to be romantically involved with Xinlu..

He's not gonna grape our precious Yuri right!?
